Abstract
The utility model discloses a kind of valve actuator, comprise housing (11), the worm gear (10) and worm screw (8) that cooperatively interact is provided with in described housing (11), described worm gear (10) arranges in described housing (11) by the axle sleeve (16) be located in housing (11), described worm screw (8) is arranged in described housing (11) by worm shaft (3), and described worm screw (8) is straight wide toroid.Valve actuator of the present utility model, in the process of Open valve, ensures that transmission is more steady, improves working life and the mechanical efficiency of this device; Decrease the unloaded gap because accumulated error causes and bearing capacity.And define good lubricating condition, decrease the receptance of error; More perfect self-locking property.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of valve actuator.
Background technique
Current domestic valve actuator, employing be the driven Design of common worm and wheel, this design has run for many years.But also cruelly spill its corresponding shortcoming, transmission efficiency is low, transmission is not steady, thus reduces the working life of valve actuator.
The utility model adopts the driven Design of hindley worm and worm gear, change the defect in valve actuator running of the driven Design of common worm screw completely, make valve actuator more steady in practical process, and improve working life and the mechanical efficiency of valve actuator.
Model utility content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of valve actuator, ensures in use more steady, reduces error sensitivity, improve mechanical efficiency and the working life of product.
For achieving the above object, the technical solution adopted in the utility model is as follows: provide a kind of valve actuator, comprise housing, the worm gear cooperatively interacted and worm screw is provided with in described housing, described worm gear arranges in described housing by the axle sleeve be located in housing, described worm screw is arranged in described housing by worm shaft, and described worm screw is straight wide toroid.
Further, affixed indicator panel on the outer side surface of described worm gear, described indicator panel is provided with pointer.
Further, the two ends of described worm shaft wear on the housing respectively by sliding bearing.
Further, one end of described worm shaft is sealed by protective plug and described housing, and the other end is sealed by seal ring and described housing.
Further, one end of described worm shaft is provided with the handwheel driving described worm screw to rotate.
Further, described worm screw is left hand worm or right hand worm.
The beneficial effects of the utility model are: the utility model is by the driven Design of common for original valve door drive worm screw, change over the driven Design of hindley worm, increase area of contact and the bearing capacity of the flank of tooth, ensure that the stationarity of transmission, improve this drive unit mechanical efficiency; The utility model, because increasing the area of contact of the flank of tooth, so form good lubricating condition, decreases error sensitivity, improves the working life of this drive unit, simultaneously also more perfect self-locking property.According to customer demand by adopting left hand worm or right hand worm, the mounting point of valve actuator can be changed, and not violate the regulation of drive unit handwheel direction perpendicular to duct orientation when the utility model is installed.

Embodiment
Below in conjunction with Figure of description, embodiment of the present utility model is described in further detail.
As Figure 1-4, it is the valve actuator that the utility model provides, comprise housing 11, intermeshing worm gear 10 and worm screw 8 is provided with in housing 11, worm gear 10 arranges in housing 11 by the axle sleeve 16 be located in housing 11, worm screw 8 is arranged in housing 11 by worm shaft 3, and worm screw 8 is fixed on worm shaft 3 by screw 7.In order to increase area of contact and the bearing capacity of the flank of tooth, improve the smoothness of valve actuator in actual application, worm screw 8 adopts straight wide toroid.
In order to meet the user demand of client, worm screw 8 can adopt left hand worm or right hand worm, thus can change the installation direction of product.But do not change the regulation of drive unit handwheel direction perpendicular to duct orientation.
The two ends of worm shaft 3 are fixed on housing 11 respectively by sliding bearing 5.In addition, in order to ensure the sealability of this device, one end of worm shaft 3 is provided with protective plug 9, and the other end of worm shaft 3 is provided with seal ring 4.In order to ensure worm screw moving axially in housing, being respectively equipped with between the two ends of worm screw and housing and adjusting packing ring 6.
One end of worm shaft 3 is provided with the handwheel 1 driving worm screw 8 to rotate, and handwheel 1 is fixed on worm shaft 3 by straight pin 2.By rotation hand wheel 1, worm screw 8 and worm gear 10 is driven to rotate, thus can opening/shutting valve.The utility model is not limited to handwheel 1 and drives, and also can pass through motorized motions or pneumatic drive, namely connects electric driver or air driving device in one end of worm shaft 3.
Be provided with indicator panel 15 outside housing 11, this indicator panel 15 is connected with the wheel body of worm gear 10.Ensure that operator just can observe the angle of swing of valve in outside, thus the size of valve openings can be judged.
Housing 11 is provided with cap 12, and housing 11 and cap 12 are bolted.Sealing between housing 11 and cap 12, is provided with rubber seal 13 and seal ring 14 between housing 11 and cap 12.
Housing 11 of the present utility model and cap 12 all adopt die casting aluminium, lightweight, compact structure, exquisite appearance.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technology thereof, then the utility model is also intended to comprise these change and modification.
